以下未经说明,listctrl默认view 风格为report

相关类及处理函数

MFCCListCtrl

SDK:以 “ListView_”开头的一些宏。如 ListView_InsertColumn

1. CListCtrl 风格

      LVS_ICON: 为每个item显示大图标
      LVS_SMALLICON:
为每个item显示小图标
      LVS_LIST:
显示一列带有小图标的item
      LVS_REPORT:
显示item详细资料

      直观的理解:windows资源管理器,查看标签下的大图标,小图标,列表,详细资料

2. 设置listctrl 风格及扩展风格

      LONG lStyle;
      lStyle = GetWindowLong(m_list.m_hWnd, GWL_STYLE);//
获取当前窗口style
      lStyle &= ~LVS_TYPEMASK; //
清除显示方式位
      lStyle |= LVS_REPORT; //
设置style
      SetWindowLong(m_list.m_hWnd, GWL_STYLE, lStyle);//
设置style
      DWORD dwStyle = m_list.GetExtendedStyle();
      dwStyle |= LVS_EX_FULLROWSELECT;//
选中某行使整行高亮(只适用与report风格的listctrl
      dwStyle |= LVS_EX_GRIDLINES;//
网格线(只适用与report风格的listctrl
      dwStyle |= LVS_EX_CHECKBOXES;//item
前生成checkbox控件
      m_list.SetExtendedStyle(dwStyle); //
设置扩展风格
     
注:listviewstyle请查阅msdn
     

3. 插入数据

      m_list.InsertColumn( 0, "ID", LVCFMT_LEFT, 40 );//插入列
      m_list.InsertColumn( 1, "NAME", LVCFMT_LEFT, 50 );
      int nRow = m_list.InsertItem(0, “11”);//
插入行
      m_list.SetItemText(nRow, 1, “jacky”);//
设置数据

4. 一直选中item

    选中style中的Show selection always,或者在上面第2点中设置LVS_SHOWSELALWAYS

5. 选中和取消选中一行

    int nIndex = 0;
    //
选中
    m_list.SetItemState(nIndex, LVIS_SELECTED|LVIS_FOCUSED, LVIS_SELECTED|LVIS_FOCUSED);
    //
取消选中
    m_list.SetItemState(nIndex, 0, LVIS_SELECTED|LVIS_FOCUSED);

6. 得到listctrl中所有行的checkbox的状态

      m_list.SetExtendedStyle(LVS_EX_CHECKBOXES);
      CString str;
      for(int i=0; i       {
           if( m_list.GetItemState(i, LVIS_SELECTED) == LVIS_SELECTED || m_list.GetCheck(i))
           {
                str.Format(_T("
%d行的checkbox为选中状态"), i);
                AfxMessageBox(str);
           }
      }

7. 得到listctrl中所有选中行的序号

方法一:
      CString str;
      for(int i=0; i       {
           if( m_list.GetItemState(i, LVIS_SELECTED) == LVIS_SELECTED )
           {
                str.Format(_T("
选中了第%d"), i);
                AfxMessageBox(str);
           }
      }

      方法二:
      POSITION pos = m_list.GetFirstSelectedItemPosition();
      if (pos == NULL)
           TRACE0("No items were selected!\n");
      else
      {
           while (pos)
           {
                int nItem = m_list.GetNextSelectedItem(pos);
                TRACE1("Item %d was selected!\n", nItem);
                // you could do your own processing on nItem here
           }
      }

8. 得到item的信息

      TCHAR szBuf[1024];
      LVITEM lvi;
      lvi.iItem = nItemIndex;
      lvi.iSubItem = 0;
      lvi.mask = LVIF_TEXT;
      lvi.pszText = szBuf;
      lvi.cchTextMax = 1024;
      m_list.GetItem(&lvi);

      关于得到设置item的状态,还可以参考msdn文章
      Q173242: Use Masks to Set/Get Item States in CListCtrl
              

9. 得到listctrl的所有列的header字符串内容

      LVCOLUMN lvcol;
      char  str[256];
      int   nColNum;
      CString  strColumnName[4];//
假如有4

      nColNum = 0;
      lvcol.mask = LVCF_TEXT;
      lvcol.pszText = str;
      lvcol.cchTextMax = 256;
      while(m_list.GetColumn(nColNum, &lvcol))
      {
           strColumnName[nColNum] = lvcol.pszText;
           nColNum++;
      }

10. 使listctrl中一项可见,即滚动滚动条

    m_list.EnsureVisible(i, FALSE);

11. 得到listctrl列数

    int nHeadNum = m_list.GetHeaderCtrl()->GetItemCount();

12. 删除所有列

      方法一:
         while ( m_list.DeleteColumn (0))
      
因为你删除了第一列后,后面的列会依次向上移动。

      方法二:
      int nColumns = 4;
      for (int i=nColumns-1; i>=0; i--)
          m_list.DeleteColumn (i);

13. 得到单击的listctrl的行列号

      添加listctrl控件的NM_CLICK消息相应函数
      void CTest6Dlg::OnClickList1(NMHDR* pNMHDR, LRESULT* pResult)
      {
           //
方法一:
           /*
           DWORD dwPos = GetMessagePos();
           CPoint point( LOWORD(dwPos), HIWORD(dwPos) );
  
           m_list.ScreenToClient(&point);
  
           LVHITTESTINFO lvinfo;
           lvinfo.pt = point;
           lvinfo.flags = LVHT_ABOVE;
    
           int nItem = m_list.SubItemHitTest(&lvinfo);
           if(nItem != -1)
           {
                CString strtemp;
                strtemp.Format("
单击的是第%d行第%d", lvinfo.iItem, lvinfo.iSubItem);
                AfxMessageBox(strtemp);
           }
          */
  
          //
方法二:
          /*
           NM_LISTVIEW* pNMListView = (NM_LISTVIEW*)pNMHDR;
           if(pNMListView->iItem != -1)
           {
                CString strtemp;
                strtemp.Format("
单击的是第%d行第%d",
                                pNMListView->iItem, pNMListView->iSubItem);
                AfxMessageBox(strtemp);
           }
          */
           *pResult = 0;
      }

14. 判断是否点击在listctrlcheckbox

      添加listctrl控件的NM_CLICK消息相应函数
      void CTest6Dlg::OnClickList1(NMHDR* pNMHDR, LRESULT* pResult)
      {
           DWORD dwPos = GetMessagePos();
           CPoint point( LOWORD(dwPos), HIWORD(dwPos) );
           m_list.ScreenToClient(&point);
           LVHITTESTINFO lvinfo;
           lvinfo.pt = point;
           lvinfo.flags = LVHT_ABOVE;
  
           UINT nFlag;
           int nItem = m_list.HitTest(point, &nFlag);
           //
判断是否点在checkbox
           if(nFlag == LVHT_ONITEMSTATEICON)
           {
                AfxMessageBox("
点在listctrlcheckbox");
           }
           *pResult = 0;
      }

15. 右键点击listctrlitem弹出菜单

      添加listctrl控件的NM_RCLICK消息相应函数
      void CTest6Dlg::OnRclickList1(NMHDR* pNMHDR, LRESULT* pResult)
      {
           NM_LISTVIEW* pNMListView = (NM_LISTVIEW*)pNMHDR;
           if(pNMListView->iItem != -1)
           {
                DWORD dwPos = GetMessagePos();
                CPoint point( LOWORD(dwPos), HIWORD(dwPos) );
   
                CMenu menu;
                VERIFY( menu.LoadMenu( IDR_MENU1 ) );
                CMenu* popup = menu.GetSubMenu(0);
                ASSERT( popup != NULL );
                popup->TrackPopupMenu(TPM_LEFTALIGN | TPM_RIGHTBUTTON, point.x, point.y, this );
           }
           *pResult = 0;
  }

16. item切换焦点时(包括用键盘和鼠标切换item),状态的一些变化顺序

      添加listctrl控件的LVN_ITEMCHANGED消息相应函数
      void CTest6Dlg::OnItemchangedList1(NMHDR* pNMHDR, LRESULT* pResult)
      {
           NM_LISTVIEW* pNMListView = (NM_LISTVIEW*)pNMHDR;
           // TODO: Add your control notification handler code here
              CString sTemp;
            if((pNMListView->uOldState & LVIS_FOCUSED) == LVIS_FOCUSED &&  (pNMListView->uNewState & LVIS_FOCUSED) == 0)
           {                sTemp.Format("%d losted focus",pNMListView->iItem);           }          

 else if((pNMListView->uOldState & LVIS_FOCUSED) == 0 &&
               (pNMListView->uNewState & LVIS_FOCUSED) == LVIS_FOCUSED)
           {
                sTemp.Format("%d got focus",pNMListView->iItem);
           }
            if((pNMListView->uOldState & LVIS_SELECTED) == LVIS_SELECTED && (pNMListView->uNewState & LVIS_SELECTED) == 0)
           {
                sTemp.Format("%d losted selected",pNMListView->iItem);
           }
           else if((pNMListView->uOldState & LVIS_SELECTED) == 0 &&
            (pNMListView->uNewState & LVIS_SELECTED) == LVIS_SELECTED)
           {
                sTemp.Format("%d got selected",pNMListView->iItem);
           }
              *pResult = 0;
      }

           if (nPos != -1)
           {
                strPath = strFileName.Left(nPos);
                strFileName = strFileName.Mid(nPos + 1);
           }
             // insert to list
           int nItem = m_list.GetItemCount();
